Over five hours, the music works a strange effect on the listener. The intervening decades of minimalist and ambient music have made us familiar with the concepts of long durations, tonal stasis, consistent dynamics, repetitions, but November uses these techniques in an unusual way. The sense of continuity is very strong, but there is no fixed pulse and few strict repetitions. The slowness, spareness and use of silence, with an organic sense of rhythm, make it seem very similar in many respects to Morton Feldman’s late music. The harmonic language, however, is very different. Johnson’s piece uses clear, familiar tonality to play with our expectations of the music’s ultimate direction, whereas Feldman’s chromatic ambiguity seeks to negate any feeling of movement in harmony or time.
